Antiplanar shear problem for a crack between dissimilar nonhomogeneous isotropic elastic layers

Abstract

This paper deals with the problem of determining the stress intensity factor when two dissimilar nonhomogeneous bonded elastic layers have a crack at the interface. It is assumed that the faces of the crack are subjected to prescribed antiplane shear stress. The mixed boundary value problem is reduced to a singular integral equation of the second kind which is further reduced by using Chebyshev polynomials, to a system of algebraic equations. Numerical results for the stress intensity factor are presented in the form of graphs.
